Answer:

150 pennies were lost altogether

Step-by-step explanation:

Let the initial number of pennies owned by Dante be x pennies

Let the initial number of pennies owned by Mia be y pennies

Mathematically ;

x + y = 350 •••••••(i)

So after losing half, dante will have x/2 pennies left.

Mia lost 1/3 so she will have 2/3y left

So after all the losses, they both had equal amount of pennies

This means that;

x/2 = 2y/3

Cross multiply;

3x = 4y •••••••(ii)

Let’s solve both equations simultaneously;

From i , x = 350-y

Substitute this into equation ii

3(350-y) = 4y

1050-3y = 4y

7y = 1050

y = 1050/7

y = 150

since x = 350-y

x = 350-150 = 200

Now Dante loss x/2 = 200/2 = 100

Mia lost 1/3y = 1/3 * 150 = 50

Total pennies lost = 100 + 50 = 150

What are the solutions of the equation x^4-9x^2+8=0? Use u substitution to solve.
vodka [1.7K]

Answer:

The answer is the second option

Step-by-step explanation:

Let u=x^2.

( {x}^{2} ) {}^{2}  - 9( {x}^{2} ) + 8( {x}^{2} ) {}^{0}

{u}^{2}  - 9u + 8

(u - 1)(u - 8)

u = 1

u = 8

Set this equal to x^2

{x}^{2}  = 1

x = 1

or

x =  - 1

{x}^{2}  = 8

x = 2 \sqrt{2}

or

x =  - 2 \sqrt{2}

Harold earns $10.50 per hour working at a doctor's office. On Monday he spent 1 5/12 hours filing paperwork, 1 3/4 sending email
Lana71 [14]

Answer:

the total earnings is $58

Step-by-step explanation:

The computation of earnings is shown below:

= Time spent in filling paperwork + time spent in sending emails + time spent in making appointments

= (1 5 ÷ 12 × $10.50)  + (1 3 ÷ 4 × $10.50)  + (2 1 ÷ 3 × $10.50)

= 14.875 + 18.375 + 24.50

= $57.75

Hence, the total earnings is $58

The same is to be considered
